This is 8th grade science ‍♀️ Question :
question 2
Satellite
Crash 1
Crash 2
Black Asteroid: more mass
Slowed down by 2 km/s
Gray Asteroid: less mass
Slowed down by 2 km/s
1. A satellite was in two separate crashes. In both crashes, the satellite had the same mass. Engineers want to know
about the speed and direction of the satellite after the crashes. Why would the crash affect the motion of the
satellite, and which crash caused a greater change in motion for the satellite?

The answer is a 0.64 volts

Sorry i don’t know what to do

W= fd
where f is an applied force and d is the distance over which it is applied. when a parachuting skydiver is at constant velocity, he is experiencing "terminal velocity", the point at which his acceleration down is canceled out by air resistance. that means that the resisting force of the air is equal to his weight, but in the opposite direction. with this, we can solve for the work done by the force.
w = fd
w = (92.0)(9.81 m/s^2) (325)
w= 2.93 x 10^5 j
the value for work in this case is positive because it is pushing up on the skydiver, who has a downward force of gravity.
therefore the answer is 2.93 x 10^5 j
